NCP81161MNTBG

Overview

The NCP81161MNTBG is a VR12.5 MOSFET driver manufactured by onsemi. It is designed to drive external power MOSFETs in high-performance voltage regulator applications. The device operates within a supply voltage range of 4.5 V to 20 V and supports switching frequencies up to 1 MHz. It features integrated dead-time control and protection mechanisms including over-current, over-temperature, and under-voltage lockout. The component is housed in a compact 20-pin QFN package with an exposed thermal pad for efficient heat dissipation.

Feature Summary

• Complies with Intel VR12.5 specification for multi-phase CPU core voltage regulation
• Integrates adaptive dead-time control to minimize conduction losses
• Includes comprehensive protection features such as over-current and over-temperature monitoring

Applications

• Multi-phase CPU core voltage regulators
• Server and workstation power delivery systems
• High-density point-of-load conversion architectures

Procurement Notes

Verify the specific ordering suffix MNTBG to confirm the tape-and-reel packaging configuration and pin-out compatibility. Ensure the procurement channel provides valid traceability documentation. Confirm that the component meets current environmental compliance standards required for your manufacturing process before finalizing orders.

Selection Notes

Select this component when designing systems requiring strict adherence to the VR12.5 standard for processor power management. Consider the thermal performance of the QFN package relative to your board layout and airflow conditions. Evaluate the need for external components versus the integrated protection features to optimize bill of materials cost and board space.

Part Context

This part belongs to onsemi's portfolio of power management integrated circuits focused on computing applications. It serves as a gate driver stage within a larger multiphase controller system.
